A baby whale gets lost from his mother while swimming through a large underwater canyon. Frantically the baby whale yells for his mommy. 1.5 seconds later, the whale hears his yell's ECHO from the canyon wall. How far is it to the canyon wall? The speed of sound in water is 1500 m/s.

d = V*t = 1500m/s * 1.5/2 = 1125 m.

To determine the distance to the canyon wall, we can use the speed of sound in water and the time it takes for the echo to reach the baby whale.

First, let's calculate the time it takes for the sound to travel to the canyon wall and back to the baby whale:

Since the sound needs to travel twice the distance (to reach the wall and then back), we can divide the total time (1.5 seconds) by 2 to get the time it takes for sound to travel one way:

Time = 1.5 seconds / 2 = 0.75 seconds

Next, let's calculate the distance to the canyon wall using the speed of sound in water:

Distance = Speed × Time

Distance = 1500 m/s × 0.75 s = 1125 meters

Therefore, the distance to the canyon wall is 1125 meters.
